Reason 6,784 why Europe has the U.S. whipped in terms of energy efficiency: We've had no train system worth a damn—until now. For your next trip, consider the two-year-old, five-star GrandLuxe Rail line, which hits cities like Las Vegas and parks like Yellowstone and Zion. grandluxerail.com

Gaia Napa Valley, the only LEED Gold–certified hotel in the U.S., has adopted the climate-change crisis as religion: Even the Gideons have to compete for drawer space with copies of An Inconvenient Truth. If that irks you, unwind with a hot-stone massage at Spa Gaia, or take a trip to the Madonna Estate winery, a fourth-generation organic vineyard just ten miles from the hotel. The pinot noir will make you forget all about global warming.
